vSIPHON WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 572,575, dated December 8, 1896.

Application filed October 21,1890. Serial No. 368,859. (No model.)

To all whom, it may concern.-

Beit known that I, WILLIAM SCOTT, a citizen of the United States of America, and a resident of the town of Medford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Siphon Water-Closets, of which the following is a full, clear, and exact description.

This invention in siphon water-closets, in substance, consists, irst, of an earthenware bowl having its pedestal chambered and othcrwise adapted to receive and practically to cover and inclose a metal pipe and to allow of its proper connection to the bowl at its discharge-opening and to the waste-pipe;

second, of means to connect a metal pipe to an earthenware bowl at the disch arge-opening of the latter; third, of an improved lever by which to open the tank-valve to discharge the water of the tank, and, fourth, of an improve- Inent in the short leg of the Siphon-pipe of the tank, all substantially as hereinafter described.

In the drawings forming part of this specification,Figure I is a side elevation of the siphon water-closet. Fig. 2 is a central vertical section from front to rear of the closet, Fig. 1. Fig. 3 is a horizontal section, line 3 3, Fig. 2. Fig. 4 is a perspective view, enlarged, of the packing-ring. Fig. 5 is a perspective view, enlarged, of the split ring. Fig. Gis a central vertical section, enlarged, of the split and packing rings placed together. Fig. 7 is a plan view ofthe tank, its Siphon-pipe, valve to said pipe, and lever to open said valve. Fig. S is a longitudinal vertical section of the tank and in part a side view of the siphonpipe and a vertical section of the lower and open end of short leg of said pipe. Fig. 9 is a side View of the operating-lever for valve of tank.

In the drawings, A represents the upper or bowl portion, and A2 is the lower or pedestal portion, of an carthenware or other such like bowl. The bowl A is formed, as usual, to have water entered into it from a supply-pipe B,

and out at an opening A5, all substantially as well known. l

As this invention is particularly shown, the discharge-opening A5 of bowl is connected to one end of a water-trap E2, which makes part of a cast-iron or other suitable pipe E, and has its opposite end continued upwardly and rounded at E3 and thence downwardly at E4, of suitable length to lead through and to pro ject below the floor F of the room on which the bowl is placed, and below the Hoor to be enteredinto the under side of a shouldered hub of a waste-pipe and therein packed tightly in any suitable and well-known manner.

Y The metal pipe E, as shown, extends from rear to front of and underneath the bowl A, and it lies within a chamber Ai of the pedestal A2. This pedestal-chamber A6, as shown, has side walls A7 A8 and a front Wall A9, and these walls are continuous j and together make the pedestal,and said metal pipe E on its upper and opposite vertical side and front portions is inclosed in said chamber, and the pipe preferably has a base E5 for its better rest on the iloorF. At the rear portion of the bowl is a horizontal projecting flange A10 at and about the discharge-opening A5 of the bowl. The rear end of the metal pipe E is presented toward the under side or face of the bowldlange A10, and it is connected to and fastened against said face of said flange, and their joint is packed all by means consisting, in substance, rst, of a metal or such like rigid iiat ring H, having a downward-projecting flange H2 around its inner edge and split diametrically and vertically into sections, joined transversely by headed screw-bolts H3, passing loosely through one and screwing into the other of adjacent vertical earpieces HLl of the ring; second, of an india-rubber or other such like compressible gasket or ring J of a shape corresponding to said Inetal ring, but preferably not split, and adapted by its flange to nt within the flange and lie upon the outer face o fthe metal ring, and, third, of headed screw-bolts K, entered through suitable holes located at intervals of said metal ring and of said compressible gasketv ring H (its sections being loosely held to-l gether by the screw-bolts H3) and the gasket- IOO J, placed in the ring, as described, are together placed around the outside of the pipe E at or near its end which is open and toward the bowl discharge-openin g A5 and then lifted to make close seat of gasket against seating-face therefor of bowl-iiange, on which the ring by turning up the screw-bolts H3 of its sections is closed about the gasket, closing itin turn tightly about and on the pipe, and then by turning up the screw-nuts K2 of the screw-bolts K, 'located in the bowl-flange, the ring and gasket are made fast to the bowl-flange, tightly closing the gasket thereagainst and as a whole securing a tight and close connection of bowl and pipe. In attaching bowl and pipe E, as stated plainly, care is to be taken that a tight and close joint is made of gasket, both with pipe and bowl-flange.

The connection of bowl and metal pipe described is advantageous in that the ring and its gasket can be adjusted lengthwise on the pipe to accommodate them to varying relative heights of the bowl-lian ge and the open end of metal pipe, all so liable to occur because of Variations in the height and in the form of the jointing-face of the bowl-flange, the results of molding the bowl, and otherwise, all as well known. Again, a chambering of the pedestal and a seat-facing of an earthenware bowl, all substantially as described, secu-res not only a practical inclosure of a metall pipe E, but also permits connection of bowl and said pipe to be readily made and without eithe-r disiigurement of the bowl er of its pedestal, or of exposure to any appreciable degree of the pipe.

The bowl described, in combination with a metal pipe E, having a water-trap E2, as particularly explained, secures a double trapping of the discharge-passage of the bowl and a column of air between said two traps, but this of itself is not new. A

So far as has been in detail explained it is obvio-us that the water-trap of the pipe E may be dispensed with, again, that the direction of the run of the pipe E as to the bowl-pedestal and the chambering of the pedestal may be changed to accommodate varying positions of the discharge-opening of the bowl and of the waste-pipe to be connected by the pipe E 5 again, that the seating and jointing face of the bowl for connection with the pipe E may be varied in position. to suit a different position from that shown of the open end of the pipe E, and, again, that other means of c0nnection of the pipe E and bowl maybe used, and all without departing, in substance, from the features of this invention, to which such obvious modications may and do pertain.

L is an ordinary hinged valve located in the tank and arranged, as usual, to be opened for passage through the pipe B of Water from the tank to the bowl.

M is an upward extension of the pipe B from 'valve L, and this extension at its upper end of the tank, and all so that the whole makes a siphon-pipe for a discharge by its siphon action of the contents of the tank, irst having set the water in motion through pipe B by an opening and then closing of valve L of said pipe. The downward extension M3 is the short leg, and .the remainder M2 M and its continuation B is the long leg, of the siphonpipe, and heretofore as siphon-pipes in siphon water-closets have been arranged and constructed their siphonic action is and can only be broken either partially or wholly by the entrance of air at the open end of the short leg of the siphon-pipe, thus causing oftentimes (and, in fact, most generally) such a flow of water through the bowl that at the end of the water-iio-w no substantial amount of water can or will be left standing in the trap of the bowl. Y

This invention aims to and practice and experience have shown that it avoids the objection stated, and to that end and in this relation the devices ofthe invention consist of a series of perforations a a a, shown as three in number, but which may be more or less than three, three, however, being found practical. These perfor-ations are located each in a different horizontal plane of one side of the short leg of the siphon-pipe. Each perforation is small and the whole series taken together are of a considerably lless superficial area than the open end of said short leg. The perforations separately and together admit air to the siphon-pipe when the water of the tank has been drawn off from the tank to and below their level, and therebyis secured a gradual reduction or. breaking, or, as it were, a tempering of the force of the siphonic discharge before it is fully arrested, and all so that not only is the desired discharge in quantity of water from the tank secured, but also standing water in the bowl to the height desired, the latter result being made most sure and reliable.

N is a lever which is arranged vertically edgewise and is hung intermediately of its length ona horizontal fulcrum-pin N2 of one of the side walls of the tank C. One portion of this lever lies within and along the inner face of said side wall of the tank and the other portion projects over one end of the tank, and there a chain or such; like (not shown) is to be attached for operating it.

N3 is an arm that at one end is fastened by a set-screw NJl rigidly to the portion of the lever which lies within the tank and at its other end is over the tank-valve, to which it is connected by chain or such like. (Not shown.) -This arm N3, near its point of attachment to lever N, has two radial carpieces N 5 N 6, each in position to serve, according as the lever is fulcrurned at one or the other end of the tank, as a rest and stop, by contact with the upper edge of the tank, to the down- IOO IIO

ward movement of the portion of the lever to which the tank-valve is to be attached, as stated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

and a pedestal situated below and continuous.

along the front and each side of the bowl and shaped to form a chamber therewithin, which is open at and about said bowl-flange, in combination with a metal trap, at its receivingleg joined to said bowliiange and therefrom lying and inclosed within said pedestal-chamber substantially as described, for the purpose specied.

2. The combination with the discharge of an earthenware closet-bowl and a metal pipe in continuation of the discharge of said bowl, of appliances to join said pipe to said bowl, consisting of a iiange projecting laterally about the discharge of the bowl, a metal ring, split radially, and shaped and adapted to surround said pipe and the under side of said bowliiange, a packing ring in one piece adapted to fit within and upon the face of said split ring at the under side of said bowlflange, and means adapted to be applied to said split ring to close it above said metal pipe and to fasten it with the packing to said bowl-flange substantially as described, for the purposes specified.

3. A lever for operating valves of tanks of water-closets, made in parts,rone fulcrumed on the tank and another detachably attached to said fulcrumed part and having earpieces N5, N6, substantially as described, for the purposes speciiied.

4. In a water-closet apparatus, the combination with a metal trap, of a bowl, outlet, and hollow pedestal, all made from a single piece ofy earthenware, the pedestal inclosing the said trap and constructed to form a horizontal outwardly-extending flange at its j unction with the outlet, and means for securing together said flange and trap, substantially as described.-

5. In a water-closet apparatus, the colnbination with a metal trap, of a bowl, outlet, and hollow pedestal, all made from a single piece of earthenware, the pedestal having sides extending down to a common base-level so as to incase the trap, the outlet having a perforated outwardlyextending flange adjoining the pedestal, a packing-ring, bolts or screws projecting upwardly through the iiange and packing-ring, and eXteriorly-arranged nuts engaging with the protruding threaded ends of the bolts or screws, substantially as described.

6. yA water-closet bowl, outlet, and hollow pedestal, all made from a single piece of p earthenware, the walls of the pedestal all eX- tending down to a common base-level, and the pedestal'and outlet being constructed to form at their junction ahorizontal outwardlyextending perforated iiange, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
